Abstract
Five anthocyanins, cyanidin 3-O-(2-O-beta-xylopyranosyl-6-O-(Z)-p-coumaroyl)-beta-galactopyranoside (2), cyanidin 3-O-(2-O-beta-xylopyranosyl-6-O-(E)-p-coumaroyl)-beta-galactopyranoside (3), cyanidin 3-O-(2-O-beta-xylopyranosyl-6-O-(E)-caffeoyl)-beta-galactopyranoside (4), cyanidin 3-O-(2-O-beta-xylopyranosyl-6-O-acetyl)-beta-galactopyranoside (5), and cyanidin 3-O-(2-O-beta-xylopyranosyl-6-O-acetyl)-beta-glucopyranoside (6), together with the known cyanidin 3-O-(2-O-beta-xylopyranosyl)-beta-galactopyranoside (1), were isolated from red flowers of Camellia cultivar 'Dalicha' (Camellia reticulata) by chromatography using open columns. Their structures were subsequently determined on the basis of spectroscopic analyses, i.e., 1H NMR, 13C NMR, HMQC, HMBC, HR ESI-MS and UV-vis.Entities:
